Abstract
A lightweight flexible patient litter includes, in one example, spaced compression longerons each foldable at spaced legs, a bed between the compression longerons, and a longitudinal truss structure on each side of the litter each including a longeron, its spaced legs, and one or more flexible tension members connected thereto. One or more lateral truss structures may each include opposing legs on each side of the litter and one or more flexible tension members connected thereto. A bed truss structure may include one or more tension members.
Claims22
A lightweight foldable patient litter comprising:
- spaced compression longerons each foldable at first, second, and third spaced legs;
- a bed between the compression longerons;
- and
- a longitudinal truss structure on each side of the litter including one of the compression longerons and a flexible, foldable tension member extending from at or proximate one end of said compression longeron to at or proximate the bottom of each leg to an opposing end of said compression longeron, the flexible, foldable tension members supporting loads only in tension and not supporting loads in compression or bending.
A lightweight foldable patient litter comprising:
- a longitudinal truss structure on each side of the litter including a foldable compression longeron, a plurality of legs, and flexible, foldable tension members extending from at or proximate one end of said compression longeron to at or proximate the bottom of each leg and then to an opposing end of said compression longeron;
- and
- one or more lateral truss structures between opposing legs of the litter;
- the flexible, foldable tension members supporting loads only in tension and not supporting loads in compression or bending.
A lightweight flexible patient litter comprising:
- spaced compression longerons each foldable at spaced legs;
- a bed between the compression longerons;
- a longitudinal truss structure on each side of the litter each including one of the compression longerons, its spaced legs, and one or more flexible, foldable tension members connected thereto;
- one or more lateral truss structures between said spaced compression longerons and each including an opposing pair of said legs and one or more flexible, foldable tension members connected thereto;
- and
- bed truss panels including one or more tension members,
- the flexible, foldable tension members supporting loads only in tension and not supporting loads in compression or bending.
A lightweight foldable patient litter comprising:
- spaced compression longerons each foldable at spaced legs;
- a bed between the compression longerons;
- truss structures including flexible, foldable tension members supporting loads applied to the bed by a patient;
- a patient restraint connected to nodes of the a truss structure;
- and
- a litter restraint connected to the same nodes;
- the flexible, foldable tension members supporting loads only in tension and not supporting loads in compression or bending.
